Sinkholes can form when

A 2.3 kg block is pulled across a friction-free horizontal surface, stretching a spring that has a spring constant of 18 N/m. At the moment it is released, the block accelerates at 0.27 m/s2.

A spring is stretched from equilibrium to 0.90 m, and the work done on the spring equals 18 J. What is the value of the spring constant?

An object is moving at 5 m/s and a height of 4m. If the object has a mass of 5kg what is it mechanical energy
